View Full Version : What longest rail possible for Horseman?
I have myself modular 760mm rail. I have also seen 1m rail. Is there anything longer possible by combining two rails together?

Horseman sold this coupling plate, it was in a catalog, I bought a used one on eBay years ago
I used it once to mount two 700 mm rails with everything I had to make one long bellows
Only good if you need it

It means that it is not really stable?

If you make it yourself it can be as stout as you want.

Exactly
A very long Horseman could be built on top of a 20/80 extrusion, I have used lots of it

Good point!
I envy Americans who have easy access to these nice aluminium systems.

We do still make some things here...
What I really like about 80/20 is they will also cut to length, thread tap holes even small orders and ship quickly
They also offer offer Metric and Imperial sizing
I have a ULF camera project that has stalled, using their parts
one of these years...
Good point!

Fortunately you can buy similar profiles worldwide. I belive the system was actually invented by ›item‹ in 1980.

About buying 80/20 T-slotted extrusion. As mentioned in post #7 above, 80/20 themselves offer great service. But at a price. They sell "surplus" on amazon.com, if all that's needed is a section of extrusion and they offer the length desired, at lower prices.

Yes, it seems 1980 predates 1989
but USA can get Imperial sizes AND Metric

Given enough bellows and standards, one could hypothetically make an extension a mile long if they wanted to. I've seen it done for Sinar monorails up to about 16ft long using a steel I-beam support below. Some special micro application. I happen to have a 28 inch Horseman bellows which fits my Sinar standards, and is less susceptible to sag without a intermediate support. I make my own underlying equivalents of what has here been termed a "connector plate" using maple hardwood stock and brass thread inserts.
